Immersive displays

ABSTRACT

An immersive display includes a body, at least one display on the inside of the body for displaying images in front of at least one eye of a user, and a processor. The processor is coupled to the display and operable to obtain information utilized for displaying the images, identify a direction that a user is looking, identify a center of a field of view based on the direction that the user is looking, utilizing the information obtained, display a first portion of the images in a first area of the field of view and display a second portion of the images in a peripheral area of the field of view. The second portion of the images is displayed at one or both of a lower resolution and a lower refresh rate than the first portion of the images.

FIELD OF TECHNOLOGY

The present disclosure relates to immersive displays such asthree-dimensional (3D) displays for displaying virtual or augmentedreality environments.

BACKGROUND

Immersive displays are becoming increasingly popular for the purpose ofplaying games in a virtual reality environment. These immersive displaysmay also be utilized for applications other than gaming, including, forexample, augmented reality applications. The virtual world oraugmented-reality is currently commonly perceived by the user based ontwo images, with each of the two images displayed close to a respectiveone of the user's eyes.

Such displays are often head-mounted and in many cases block out some orall of the real environment around the user in order to immerse theuser, for example, in the virtual world. Thus, these displays mayobstruct or block the user's vision of his or her surroundings. Thevirtual world or augmented-reality is perceived by the user based onimages displayed very close to the user's eyes.

Improvements in immersive displays and applications or uses of suchimmersive displays are desirable.

BRIEF DESCRIPTION OF THE DRAWINGS

Embodiments of the present disclosure will now be described, by way ofexample only, with reference to the attached Figures, in which:

FIG. 1 is a system for providing a multi-user virtual event;

FIG. 2 is a simplified block diagram of an example of an immersivedisplay of the system of FIG. 1 ;

DETAILED DESCRIPTION

For simplicity and clarity of illustration, reference numerals may berepeated among the figures to indicate corresponding or analogouselements. Numerous details are set forth to provide an understanding ofthe examples described herein. The examples may be practiced withoutthese details. In other instances, well-known methods, procedures, andcomponents are not described in detail to avoid obscuring the examplesdescribed. The description is not to be considered as limited to thescope of the examples described herein.

Because the display or displays of an immersive display may be veryclose to the user's eyes when the immersive display is worn by the user,the displays may render images and video in stereoscopic 3D to areas ofthe eyes that normally are presented with static non-stereoscopic 3Dimagery, such as that part of a person's vision that normally sees theperson's nose in one eye, and only monocular vision of the environmentin that part of their field of view from the other eye. Presentation ofstereoscopic 3D in areas not accustomed to seeing such imagery will veryoften cause motion sickness for the user wearing the display. Similarly,lack of the point of reference, which is removed when the nose and othernormally static imagery that a person is accustomed to seeing in eachseparate eye is replaced with imagery from an immersive display, oftencauses the wearer to feel disoriented and also contributes to motionsickness. Additionally, a very high resolution, or large number ofpixels, and a very high refresh rate is desirable in order to displayimages with sufficient clarity for virtual or augmented reality. Suchhigh resolution and high refresh rate increases the demands on deviceresources such as processing power, memory, and bandwidth to transferinformation to the immersive display.

The following describes an immersive display and a method of operatingthe immersive display. The method includes obtaining informationutilized for displaying a first image in front of a first eye and asecond image in front of a second eye of a user of the immersivedisplay, excluding part of the information to yield adjusted informationto occlude or replace first information from a first area of the firstimage and second information from a second area of a second image whendisplayed on the immersive display, and providing the adjustedinformation for displaying the first image absent the first area or inwhich a static image is displayed and the second image absent the secondarea or in which a static image is displayed on the immersive display.Thus, the display may replace the information for display in the firstarea with a static image to simulate, for example, a nose. Similarly,the display may replace the information for display in the second areawith a static image to simulate, for example, a nose.

The following also describes a method of providing information fordisplay on a display of an immersive display that includes obtaininginformation utilized for displaying a first image in front of a firsteye and a second image in front of a second eye of a user of theimmersive display, identifying a first area of the first image and asecond area of the first image and identifying a third area of thesecond image and a fourth area of the second image, and displaying thefirst area of the first image and the third area of the second imageutilizing first display attributes and displaying the second area of thefirst image and the fourth area of the second image utilizing seconddisplay attributes. The second display attributes differ from the firstdisplay attributes.

A system 100 for providing information for display on an immersivedisplay is illustrated in FIG. 1 . The system includes servers 102 thatare coupled to a network 104 or networks, which includes the internetand may optionally include a cellular network through which severalclient devices, nodes, or terminals may be connected. In the example ofFIG. 1 , five client devices are coupled to the network 104, includingdesktop computers 106, 108, 110, a laptop computer 112 which is coupledto the network wirelessly through a modem 114, and a smartphone 116. Theservers 102 store and execute software or firmware and communicate andcooperate with software and firmware on the client devices 106, 108,110, 112, 116 via the network. The software and firmware on the clientdevices 106, 108, 110, 112, 116 also communicate and cooperate withsoftware and firmware on respective immersive displays that may be wornby the users.

The servers 102, utilizing the software or firmware, provide the virtualenvironment, which may be a three-dimensional virtual environment. Theenvironment may be any suitable environment for a game, a social networkor interaction site, a meeting environment, such as a boardroom ormeeting room, a classroom, a conference room or any other room or otherscene. The virtual environment provided is dependent on the applicationand may be dependent on any other suitable factor such as the number ofparticipants.

The servers 102 also manage authorization of users via client devices tofacilitate participation in the virtual environment by avatarsrepresenting the users. The avatars enter the virtual environment totake part in or attend an event such as a game, a social network eventor interaction, a meeting, class, conference or other event.

The images, including the environment, may be provided to the clientdevices 106, 108, 110, 112, 116 for display utilizing the immersivedisplays, which may be, for example, head-mounted displays worn by theusers.

A simplified block diagram of an example of an immersive display 200 isshown in FIG. 2 . The immersive display 200 includes multiplecomponents, such as a main processor 202 that controls the overalloperation of the immersive display 200.

The main processor 202 interacts with other components of the immersivedisplay 200, including, for example, a temporary storage device 204, amemory 206, a display device 208, a speaker 210, an auxiliaryinput/output (I/O) subsystem 212, external cameras 214, one or moreinternal cameras 216, one or more microphones 218, anorientation/movement sensor 220, one or more proximity sensors 222, acommunication subsystem 224, short-range communications 226, a powersource 228, and, optionally, other subsystems 230.

The temporary storage device 204 may be, for example, Random AccessMemory (RAM) that stores data that is processed by the main processor202. The memory 204, such as flash memory, is utilized for persistentstorage.

The immersive display 200 provides video output through the display 208,which includes an interface, a controller and a pair of displays todisplay images. The images displayed include a respective image in frontof each one of the user's eyes such that a right side image is displayedin front of a user's right eye and a left side image is displayed infront of a user's left eye. In addition to the display 208, output isprovided via the speaker 210 or other audio output such as headphones orearphones. The auxiliary input/output (I/O) subsystem 212 includes aninterface through which, for example, a USB controller or otherperipheral device may be connected.

Input to the immersive display may be provided via external sensors orinput devices such as the external cameras 214 mounted on the body ofthe immersive display 200. The external cameras 214 may include multiplecameras to obtain images extending around the user, i.e., 360° aroundthe user. The external cameras 214 may also include cameras to obtainimages in an upward direction from the user, and in a downward directionfrom the user. Each of the cameras includes the functional componentsfor operation of the camera, including the lens, the image sensor, and,optionally, a light sensor and light source, such as infrared lightemitting diodes (LEDs). Thus, the cameras provide images of the user'senvironment or surroundings. The cameras may be one or more of visuallight cameras, 3D sensing cameras, light field cameras, forward lookinginfrared cameras, near infrared cameras, ultraviolet cameras, or otherimaging devices.

The terms upward and downward are utilized herein to generally describedirection of view of the external cameras 214 relative to the user whenthe immersive display is worn by the user and the user is in an uprightposition, and such terms are not otherwise limiting.

The one or more internal cameras 216, referred to herein as the internalcamera 216, may be mounted on an inside of the body of the immersivedisplay and includes the functional components for operation of eachinternal camera, including the lens, the image sensor, and a lightsource, which may be a light source in the non-visible spectrum, such asinfrared LEDs. Although the interior of the immersive display 200 may bedark because exterior light is blocked out or partially blocked out, thelight source provides sufficient light for use of the internal camera216.

The one or more microphones, referred to herein as the microphone 218,may also be mounted in the body of the immersive display 200 to provideinput by converting audible information to electrical signals, which maybe processed by the main processor 202 and may be transmitted to anotherelectronic device to which the immersive display 200 is coupled. Forexample, the immersive display may be coupled to a smart-phone, a laptopcomputer, a tablet, a desktop computer, a game device, and any othersuitable electronic device.

The main processor 202 also receives signals from theorientation/movement sensor 220, which is coupled to the body of theimmersive display 200. The orientation/movement sensor may be, forexample, an accelerometer, a gyro sensor, or any other suitable sensoror combination of sensors that is or are utilized to detect direction ofmovement, direction of gravitational forces, and reaction forces so asto determine, for example, the orientation of the immersive display 200and the movement of the immersive display 200.

The one or more proximity sensors, referred to herein as the proximitysensors 222, may provide additional input to the main processor 202 todetect the presence of objects that are near or proximal to the sensorand thus to the user when the immersive display 200 is in use. Theproximity sensors 222 may be any suitable proximity sensors such as acapacitive or photoelectric proximity sensor.

The communication subsystem 224 receives signals from another electronicdevice such as the client devices 106, 108, 110, 112, 116 shown in FIG.1 , and sends signals to the other electronic device to which theimmersive display is coupled. Thus, for example, the signals from themicrophone 218 or signals from the external cameras 216 or from theinternal camera 216 may be sent via the communication subsystem 224. Thecommunication subsystem 224 is also responsible for receiving signalsfrom the other electronic device for processing by the main processor202 to cause images, which may include video, to be displayed on thedisplay 208 and for audio to be output through the speaker 210.

The immersive display 200 optionally includes short-range communications226 to perform various communication functions. For example, theimmersive display 200 may include Bluetooth or infrared (IR)communications capability, for example, for communicating with aperipheral device or accessory.

The power source 228 may be one or more rechargeable batteries or a portto an external power supply to power the immersive display 200.

The systems and subsystems that interact with the main processor 202 andare described herein are provided as examples only. Other subsystems 230may also interact with the main processor 202.

Utilizing the images from the internal camera 216, the main processor202 may be operable to track eye motion. To track eye motion, the user'spupils may be tracked when the immersive display 200 is in use. The eyemotion tracking may also facilitate determination of what a user islooking at, for example, by triangulation to determine depth of anobject or image that a user is looking at. Alternatively, the internalcamera 216 may identify or track changes in muscles or muscle motionaround at least one of the user's eyes to identify movement of the eye,or may track changes in shape of a lens of an eye or changes in shape ofthe lens of each eye to identify a focal distance, facilitatingidentification of the depth of focus of a user.

In one aspect, variable focal optical elements, such as the SuperFocus™glasses may be utilized and controlled digitally to create a morerealistic blur effect. Areas that are set to be blurred may be renderedwith fewer pixels.

Based on the eye motion tracking, the direction that the user is lookingmay be identified. The direction may be, for example, an angle orangles, such as angular offset or offsets from straight ahead. Thus,when a user glances upwardly, downwardly, or to either side, thedirection is identified and the images displayed utilizing the display208 may be changed or adjusted based on the direction.

The main processor 202 is also operable to analyze the images from theinternal camera to track or identify a change in facial expression. Forexample, the main processor 202 may utilize primary facial featuretracking by tracking features such as lips, nose, and eyes.Alternatively, or in addition, movement of parts of the face may betracked. The main processor 202 may transmit facial expression data oran identification of the expression to the other electronic device towhich the immersive display 200 is coupled via the communicationsubsystem 222.

The main processor 202 is also operable to receive the image data fromthe external cameras and to transmit the data to the other electronicdevice, along with metadata for at least key frames for identifying theimage data such that the images can be stitched together to provideimages of the user's surroundings. Thus, the images from each of thecameras can be stitched together to obtain images of the user's entiresurroundings.

When viewing images without using the immersive display 200, a user'snose typically occludes part of the real space that is viewed. In otherwords, part of the real space cannot be seen without adjusting thedirection or position of the head because the user's nose is in the lineof sight or in the line of the peripheral vision. In virtual reality oraugmented reality viewed through the immersive display, correspondingareas may be occluded from display. Areas that would correspond to auser's nose are not displayed to increase the user's perception that thevirtual or augmented reality space is real. Thus, no image is displayedin the areas that would correspond to the location of a user's nose or astatic image may be displayed. By providing no image or a static imagein such areas, a stable reference is provided in the user's line ofsight and the chance of experiencing motion sickness or the severity ofthe motion sickness experienced while wearing the immersive display 200may be reduced.

In addition, because the display 208 of the immersive display 200 isvery close to the user's eyes when the immersive display 200 is worn bythe user, a very high resolution, or large number of pixels, and a veryhigh refresh rate is desirable in order to display images withsufficient clarity for virtual or augmented reality. Such highresolution and high refresh rate utilizes more processing power.Replacing parts of the images with static images to simulate a nosereduces the number of pixels for which information is processed fordisplay, thus reducing one or more of processing requirements, memoryrequirements, and bandwidth utilized to transfer information to theimmersive display.

A flowchart illustrating a method of providing information for displayon a display of an immersive display is shown in FIG. 3 . The method maybe carried out by software executed, for example, by one or more of theservers 102, by one or more of the client devices 106, 108, 110, 112,116, by the main processor 202 of the immersive display 200, or by acombination of these devices. Coding of software for carrying out such amethod is within the scope of a person of ordinary skill in the artgiven the present description. The method may contain additional orfewer processes than shown and/or described, and may be performed in adifferent order. Computer-readable code executable by at least oneprocessor to perform the method may be stored in a computer-readablemedium, such as a non-transitory computer-readable medium.

Information is obtained for displaying on the display 208 of theimmersive display 200 at 302. The information includes information fordisplaying a right side image in front of a right eye and a left sideimage in front of a left eye of a user of the immersive display 200 toprovide a virtual 3-D image for the user. The information may beinformation from an application and is utilized to display a scene froma game, a social network or interaction site, a meeting environment,such as a boardroom or meeting room, a classroom, a conference room orany other room or other scene.

Parts of the information are identified for exclusion from theinformation or for replacement with a static image at 304. The parts ofthe information that are identified correspond to a first area of theright side image and a second area of the left side image. The firstarea and the second area correspond to areas at which a user's nosewould occlude the field of vision in real space. Thus, the first area isat a left side of the right side image and the second area is at a rightside of the left side image.

Other parts of the information that correspond to other areas may alsobe identified for exclusion or for replacement with static images. Forexample, in addition to the areas that correspond to the user's nose,other areas that correspond to typical locations of cheekbones or eyesockets or both may be occluded from the field of vision. Theinformation that corresponds to these areas of each of the right sideimage and the left side image may also be identified for exclusion,which may further increase the perception that the virtual reality spaceor augmented reality space is real.

The parts of the information are removed from the information obtainedto yield adjusted information at 306. The adjusted information includesless information or data than the information obtained at 302, prior toremoving the identified information. Alternatively, the parts of theinformation are replaced with static images to simulate a user's nose.The static images may be displayed at a lower resolution and may bedisplayed at a slower refresh rate.

The adjusted information is then provided at 308 for displaying thefirst image without the first area and the second image without thesecond area, corresponding to the areas at which the user's nose ispresent. The static images may be displayed in the first area and thesecond area.

The method illustrated in FIG. 3 is continuous such that the images arecontinuously updated on the display 208 of the immersive display 200 todisplay or play virtual reality or augmented reality video on theimmersive display 200.

By providing no image or a static image in the areas that correspond tothe nose or other occluded areas, the amount of information that isrequired for displaying images on the display 208 is reduced. The amountof information required for rendering is reduced. Thus, the area of thedisplay 208 on which information is rendered is reduced. The display 208may also or alternatively be reduced in size, such that the display 208does not extend to those areas at which information is not rendered.Alternatively, the display resolution may be reduced for such areas, forexample, for rendering a static image. In one example, the amount ofinformation transmitted from the one or more servers 102 may be reduced.

As indicated above, the method illustrated in FIG. 3 and described abovemay be carried out by software executed, for example, by one or more ofthe servers 102, by one or more of the client devices 106, 108, 110,112, 116, by the main processor 202 of the immersive display 200, or bya combination of these devices.

Optionally, the static image that is displayed on occluded areas of thedisplay may be customizable or configurable by the user. For example,the static image may be configured by the user to configure attributesof the image, such as size, shape, and skin tone of the static image, tosimulate the user's nose. For example, such configuring may be carriedout by selection of options from a menu or utilizing any other suitablemethod.

According to one example, the method is carried out at one or more ofthe servers 102 such that the server obtains the information from anapplication executed at the one or more servers 102 at 302. The one ormore servers 102 also identifies the parts of the information forexclusion, including the first area of the right side image and thesecond area of the left side image at 304 and the one or more servers102 removes the information at 306 to yield adjusted information thatexcludes the identified information. The adjusted information isprovided by the one or more servers 102 at 308, to the immersive display200 by sending the adjusted information to the immersive display 200,via the respective client device.

According to another example, the method is carried out at the clientdevice 106, 108, 110, 112, 116. In this example, the client deviceobtains the information from the one or more servers 102 or from theimmersive display 200, for example, from images captured utilizing theexternal camera or cameras 216 of the immersive display 200 at 302. Theclient device 106, 108, 110, 112, 116 identifies the parts of theinformation for exclusion, including the first area of the right sideimage and the second area of the left side image at 304 and the clientdevice 106, 108, 110, 112, 116 removes the information at 306 to yieldadjusted information that excludes the identified information. Theadjusted information is provided by the client device 106, 108, 110,112, 116, to the immersive display 200 by sending the adjustedinformation to the immersive display 200 for displaying, on the display208, the right side image excluding at least the first area and the leftside image excluding at least the second area.

According to yet another example, the method is carried out at theimmersive display 200. According to this example, the main processor 202of the immersive display 200 obtains the information from the respectiveclient device 106, 108, 110, 112, 116, or from the one or more servers102 via the respective client device 106, 108, 110, 112, 116, or, forexample, from images captured utilizing the external camera or cameras216 of the immersive display 200 at 302. The processor 202 identifiesthe parts of the information for exclusion, including the first area ofthe right side image and the second area of the left side image at 304and the processor 102 removes the information at 306 to yield adjustedinformation that excludes the identified information. The adjustedinformation is provided by the processor 102, to the display 208 of theimmersive display 200 by sending the adjusted information to theimmersive display 200 for displaying the right side image excluding atleast the first area and the left side image excluding at least thesecond area.

As described above, the images displayed, utilizing the pair ofdisplays, include a respective image in front of each one of the user'seyes such that a right side image is displayed in front of a user'sright eye and a left side image is displayed in front of a user's lefteye. Rather than utilizing generally symmetrical circular, rectangularor simple geometric shaped displays designed to maximize display ofpotentially viewable areas to all areas of each eye of the user, theimmersive display may be constructed with displays that are shaped toonly display environmental imagery to those areas of each eye thattypically see such imagery in the normal course of use. For example,each display may be generally circular with the exception of a notch orarea corresponding to a user's nose. Thus, each display is shaped toocclude an area to correspond with the user's nose. The displays mayalso be shaped to occlude areas corresponding to other facial featuressuch as eye sockets and cheekbones.

Such shaped displays may be advantageous because areas of images areoccluded by the shape of each display rather than by software, reducingprocessing time. Additionally, by reducing the total area of eachdisplay compared to a geometrically simple display, the total number ofpixels of the display may be reduced compared to a circular display, forexample, while still displaying images at the same very high resolution.

Optionally, an obstruction may be inserted into the body to cooperatewith the body to simulate the nose. The obstruction may cooperate withthe body of the immersive display 200 such that the obstruction ismechanically retained in the immersive display.

According to another alternative, the body of the immersive display 200may be configured to receive obstructions to occlude areas of thedisplay. In this example, a first obstruction is insertable into thebody to cooperate with the body to occlude a first area of the firstimage and a second obstruction is insertable into the body to cooperatewith the body to occlude a second area of the second image. The firstobstruction and the second obstruction are sized and shaped to simulatea user's nose when inserted into the display to occlude the areas of thedisplay.

A flowchart illustrating another method of providing information fordisplay on a display of an immersive display is shown in FIG. 4 . Themethod may be carried out by software executed, for example, by the oneor more of the client devices 106, 108, 110, 112, 116, or by the mainprocessor 202 of the immersive display 200, or by a combination of thesedevices. Coding of software for carrying out such a method is within thescope of a person of ordinary skill in the art given the presentdescription. The method may contain additional or fewer processes thanshown and/or described, and may be performed in a different order.Computer-readable code executable by at least one processor to performthe method may be stored in a computer-readable medium, such as anon-transitory computer-readable medium.

When viewing images utilizing the immersive display 200, a highdefinition image in the center of the field of view of the user providesa sharper and more realistic image for an improved experience or morerealistic experience than a lower definition image. Peripheral areas ofvision, however, may be rendered at lower definition or slightly out offocus. In fact, corrective lens eyeglasses generally correct for visionin an area centered on the field of view, for example, in a circledirectly in front of the eye. Outside of this area, the eyeglasses maynot correct for vision or correction may be reduced such that the areasoutside the center of the field of view are out of focus or blurred forthe user. Similarly, sunglasses generally reduce the amount of sunlightcoming into an area in front of each eye of the user. However, thesunlight may still enter the eye from other areas in the user'speripheral vision, around the sunglasses and thus, these other areas mayappear overexposed. Thus, information outside of the area at the centerof the field of view, also referred to as the peripheral area, may bedisplayed at a lower resolution than the information in the area at thecenter of the field of view, or at a lower refresh rate.

Information is obtained for displaying on the display 208 of theimmersive display 200 at 402. The information includes information ordata that is utilized by the display 208 to display the images. Theinformation includes information for displaying the right side image infront of a right eye and the left side image in front of a left eye of auser of the immersive display 200 to provide a virtual 3-D image for theuser. The information may be information from an application and isutilized to display a scene from a game, a social network or interactionsite, a meeting environment, such as a boardroom or meeting room, aclassroom, a conference room or any other room or other scene.

Parts of the information utilized to display the images are identifiedat 404 for displaying different areas at different resolution. Part ofthe information utilized for displaying the right side image isidentified for displaying a peripheral area of the image at a lowerresolution compared to the remainder of the image. Part of theinformation utilized for displaying the right side image is identifiedfor displaying a peripheral area of the image at a lower resolutioncompared to the remainder of the image. For example, informationutilized to display any area that is outside a circular or ellipticalarea at the center of the field of vision may be identified as theperipheral area. Information utilized to display the peripheral area ofthe right side image and information utilized to display the peripheralarea of the left side image may be identified.

To identify the part of the information utilized to display the areas ofthe image that are outside the area at the center of the field of view,the information utilized to display the area of the image at the centerof the field of view in each of the right side image and the left sideimage may alternatively be identified, thus distinguishing between theinformation utilized to display the area of the image that is at thecenter of the field of view and the information that is utilized todisplay the areas that are outside the center of the field of view.

Optionally, the images from the internal camera 216 of the immersivedisplay 200 may be utilized by the main processor 202 to track one oreach of the user's pupils to identify the direction that the user islooking. The field of view may be identified based on the direction thatthe user is looking. For example, for each of the right side image andthe left side image, an area at the center of a field of view may beidentified by a circular or elliptical area centered on the directionthat the user is looking. The information that is utilized to displaythe area at the center of the field of view is identified, thusdistinguishing between the information utilized to display the area ofthe image that is at the center of the field of view and the informationthat is utilized to display the areas that are outside the area at thecenter of the field of view.

Alternatively or additionally, the internal camera 216 may identify ortrack changes in muscles or muscle motion around at least one of theuser's eyes to identify movement of the eye, or may track changes inshape of a lens of an eye or changes in shape of the lens of each eye toidentify a focal distance, facilitating identification of direction anddepth of focus of a user. The center of the field of view of each of theright side image and the left side image may be based on such trackingand the size of the area that is identified as the center of the fieldof view may also vary based on such tracking. For example, a smallercenter of the field of view may be identified when the depth of focus isgreater as a user is viewing an object perceived to be a greaterdistance away.

According to an alternative embodiment, information that is utilized todisplay the area at the center of the field of view may be obtained andthe information utilized to display parts of the image in the peripheralarea may be created. For example, the information utilized to displaythe pixels in the peripheral area around the area at the center of thefield of view may be created at the respective client device or at theimmersive display 200. The information may be created based onattributes of the displayed image in the area at the center of the fieldof view. Thus, the information to display the area at the center of thefield of view is received at the respective client device and immersivedisplay 200 and the information to display the peripheral area iscreated.

Information is provided to the display 208 of the immersive display 200for displaying different areas utilizing different attributes at 406.For example, the right side image and the left side image are providedto the display 208 for displaying at 406. The area of the right sideimage that is at the center of the field of view is displayed utilizingfirst display attributes. The peripheral area of the right side image,outside the area at the center of the field of view, is displayedutilizing second display attributes. Similarly, the area of the leftside image that is at the center of the field of view is displayedutilizing first display attributes and the peripheral area of the leftside image, outside the center of the field of view, is displayedutilizing a second display attribute.

For example, the areas outside each area at the center of the field ofview in each of the left side image and the right side image may bedisplayed at a lower resolution and with a lower refresh rate than eachrespective area at the centers of the field of view.

A plurality of parts of the information may be identified at 404 foreach image. For example, information to display the area at the centerof the field of vision may be identified. Information to display anintermediate area surrounding the area at the center of the field ofvision may be identified and information to display an outer peripheralarea may be identified. The information may be identified to display thearea at the center of the field of vision at the highest resolutionwhile displaying the intermediate area at a relatively lower,intermediate resolution, and displaying the outer peripheral area at aresolution that is lower than the intermediate area. In this example,three areas are identified in each of the right side image and the leftside image and each of the areas are displayed utilizing differentattributes. Other areas may be identified for displaying utilizingdifferent attributes.

The method illustrated in FIG. 4 is continuous such that the images arecontinuously updated on the display 208 of the immersive display 200 todisplay or play virtual reality or augmented reality video on theimmersive display 200.

In addition or alternatively, the immersive display 200 may includeadjustable corrective lenses positioned to be located in front of theuser's eyes when the immersive display is worn by a user. The adjustablecorrective lenses are utilized to adjustably correct the user's visionwhile the areas of the images that fall outside the lenses remainunadjusted and therefore blurred to the user who would otherwise wearcorrective lens eyeglasses.

In one aspect, where resolution, processing power, and/or other elementsare insufficient to render a full field, simulated obstructive objectsmay be placed in the field. For example, in a concert, a person sittingin front of the user may don a large virtual “hat” to obstruct theuser's view and reduce the area of the display for which the image mustbe rendered.
